To all whom t may concern:

Be it known thaty we, FRANK J. PRASIL and JAMES G. BETAR, citizens ofthe United States, residing at Chicago, in the county of Gookand Stateof Illinois, have invented a new land useful Improvement in Fabric-Renovating Brushes, of which the following is'a specification.

This invention relates to devices for reno-v vating fabrics having a napor piled-surface including such as velvet or plush.

An object of this invention resides in the production of a simple andefficient device for renovating, renewing, orrestoring fabrics byraising the projecting surface-fibers of the nap thereof, to theirnatural or original position to present a restored, live, orv

smooth surface.

Another object o'f this invention is the provision of a device fortreating fabrics with alternate steam and dry brushing.

It is also'an object to provide a device of this character which shallbe inexpensive to manufacture, simple in construction and thereforeeasily maintained.

With these and other objects in view our invention consists in the novelconstruction,

combination, association, and relative posi-` tion of the parts andmembers shown in the accompanying drawings, hereinafter described, andparticularly pointed out in the appended claims. c

Referring to the drawing in which like reference characters indicatelike or corresponding parts: F igure 1' isaf side elevation showing ourinvention and F ig. 2 is a longitudinal cross section thereof. lFig. '3wis a cross section taken on line 3-3 of Fig. 2, showing the brush andchambers. Figfl, a plan view of the brush-back showing the vsteamdischarge openings.

In the preferred construction herein illustrated our invention isembodied in a body 5 having an interior horizontal partition 6 whichdivides the interior thereof into an upper steam chamber 7 and a lowersteam chamber 8. An arched-ceiling 7A may be provided for the upperchamber 7, and a horizontal perforated ioor 8A for the lower chamber 8,although this floor could be entirely omitted by simply providing a pairof cast lugs (not shown) to the front and rear walls, markedrespectively 5A and 5B of the body 5, which lugs would retain thereto,the brush back 9, by means of screws 9B passing through the openings 9^.'llhe Hoor 8^ is provided with a plurality of perforations 8B whichregister with the perforations 9C arranged between the bristles 9D inthe brushback 9. A main steam pipe 10 constantly conveys steam into thehot or upper, steam chamber 7, a drain cock 11 is provided for thepurpose of draining the chamber 7 of any condensed steam. rllhe lower,or brush chamber 8, is supplied at intervals and as desired, with steamthrough an adjacent pipe 12 having a connection at 12A with the mainpipe 10. A valve 13 controls the steam supply to said brush chamber 8.The ends of the two steam supplying pipes pass through and are entirelyenveloped by the operating handle 111; and the end ofthe main supplypipe 10 is connected with a flexible steam hose 15 which permits themovement of the entire device. s

In the process of renovation the fabric may first be given a steambrushing involvthe fabric and removing .any particles of4 condensedsteam. l

From the above description and attached illustrations it is obvious thata simple and novel device is provided which affords the application ofalternate steam and hot brushing for renovating fabrics by thoroughlyand effectively acting upon the fibers of the nap. v

It is also clear that the body of fabricsV treated with this device isnot 'subject to shrinkage for the reason that hairsor fibers of suchfabrics are treated directly fromy above and not from the bottom throughthe bod j Ity is thought that the foregoing description andillustrations clearly disclose the invention, hence a lnore extendedexplanation'is omitted.

We claim:

1. In a device of the character described, the combination of a bodyhaving a pair of independent steam chambers, separate means forConveying steam to said chambers and a brush communicating with one ofsaid chambersl and adapted for receiving steam therefrom.

llower chamber and said brush at desired intervals of time.

4. In a device ofthe character described, the ycombination of a hollowbody having a horizontal partition therein dividing the interior thereofinto an upper chamber and a lower chamber, a main pipe adapted forconstantly conveying steam to said upper chamber, an associate pipecommunicating with said main pipe for conveying steam to said lowerchamber, a brush attached to said lower chamber and a valve for control--ling the passage of steam through said lower chamber and brush.

5. In a device of the character described, the combination of a bodyhaving an imperforate partition dividing the interior thereof into anupper chamber and a lower chamber, a main pipe adapted for constantlymaintaining steam in said upper chamber, means for draining said upperchamber, a pipe communicating with said main pipe and said lowerchamber, a valve for said pipe communicating with said lower chamber forcontrolling the passage of steam thereto, a handle adjacent said bodyenveloping both of said pipes, and a brush having a perforated back,said perforations arranged between the bristles and communicating withsaid lower chamber.

6. In a device of the character described, the combination of a bodyVhaving an imperforate partitiondividing the interior of same intoindependent upper and lower chambers, a main pipe adapted for constantlymaintaining steam in said upper chamber, a pipe controlled by a valvefor discharging steam into said lower chamber, a handle adjacentv saidbody enveloping the ends of said pipes leading to said chambers, a fixedperforated floor for said lower chamber, and a removable brush having aperforated back.

In witness whereof, we yhave hereunto subscribed our names this 10th dayof February, 19,16. FRANK J. PRASIL. JAMES G. BETAR.
